Efficiency is the cubic feet of air that can be moved in one minute if the fan were to use 1 watt of electricity, and can be used to compare energy-efficiency among different ceiling fans. The higher this number the more energy-efficient the fan is. This ceiling fan's airflow efficiency is about average, compared to fans with a 52" blade span. By comparison, other regular-sized ceiling fans with a 52" blade span typically provide an airflow efficiency ranging from 71 to 100 cubic feet per minute per watt.
